WILLIAM STUART TAIT, OF CLEVELAND, OHIO, ASSIGN'OR TO THE HYDRAULIC PRESSED STEEL COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF JOIST-BRAGKET.

Specification of Letters Patent.

Application filed November 21, 1919. Serial No. 339,746.

To all whom it may concern Be it known that I, WILLIAM STUART TAIT, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented a certain new and useful Improvement in Joist-Brackets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention is a novel construction of joist brackets adapted to be used in connection with supports for concrete forms, the object of invention being to provide a bracket capable of holding and supporting joist ends, said bracket being of such construction that the joist ends can be placed thereon at different times without dislocating the bracket or any part thereof. The

. invention consists in the details of construction hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this specification Figure 1 is a perspective view of a joist receiving member: Fig. 2 is a detail'perspective View of a strap for looking the same; 3 is a View showing the practical application of the device; and Fig. a is a sectional elevation on the line I of Fig. 3.

In carrying out my invention I employ a channeled joist receiving member A formed of sheet metal and dimensioned according to the size of joists to be employed in connection therewith. To the bottom of this member at each end thereof is attached a right angled strap B, the depending leg of which is bowed outwardly as shown at B. In connection with each right angled strap ,B I employ an L-shaped strap C, the vertical member of which is slotted and looped as shown, said slotted and looped portion of the strap 0 being adapted to be brought into registering engagement with the bowed portion B of the strap B and locked by means of a locking wedge D. In operation the bracket A is rested upon stringers E and the locking straps C are hooked under said stringers and the looped portions thereof locked to the lower ends of the straps B as previously described. The ends of the joists F and G can then be rested upon and within the bracket A and inasmuch as said bracket is securely locked against tilting movement in either direction it is obvious that either of the joists can be placed first upon the bracket.

Heretofore, so far as I am aware, it has been necessary to place the joists simultaneously upon any bracket or connecting support in order to avoid tilting.

The device herein shown is made entirely of sheet metal and is quickly and easily ma- Patented Nov. 29,1921.

nipulated either in setting up or taking down as it is obvious that it is only necessary to bring the parts into proper relation and insert the wedge in order to assemble the parts properly and that it is only necessary to remove the wedge in order to disconnect the parts.

Having thus Iclaim is 1. In a device of the kind described, the combination with a joistreceiving member,

described my invention, what of straps depending therefrom and having each a bowed portion, and straps adapted to engage the under side of stringers and having each a bowed portion, said bowed portions cooperating to define an opening, and means positioned in said opening for detachably connecting said first and last named straps.

2. In a device of the kind described, the combination with a channeled joist receiving member, s of depending straps connected thereto, the lower ends of which are bowed, and L-shaped straps having their upper ends slotted and looped, said bowed portions and said slotted and looped portion defining openings, and locking wedges adapted to be inserted in said openings thereby to connect said depending and L-shapedstraps.

In testimony whereof, I hereunto affix my WILLIAM STUART TAIT.
